The new age/spiritual interpretation of this transit is a shift in consciousness towards a more loving, open society. Venus in Roman mythology was the god of love, so symbolically this is significant in terms of shifting to a more loving paradigm.
Venus is also associated with the feminine (e.g. Men are from Mars, women are from Venus) and so its return/transit can be symbolic of increased feminine energy. I would say that we have seen an increase in feminine energy in the world since 2004 as well as further increases in rights and equality for women in a lot of places. However there's not a strong correlation since this has been going on for decades. I think that this process will continue for a while, but the pendulum is starting to swing back the other direction (discrimination against men in some circumstances - no Feminine Hygiene Product ads, I am not that retarded, # you!) - hopefully it will find a nice balance by the end of next year
In Egyptian mythology Venus is related to the Phoenix, symbolising rebirth and renewal - thus the transit is symbolic of rebirth and renewal for planet earth. When added to the Mayan's idea that from our perspective, the sun will appear to be decending through the centre of the galaxy (What they called the Birth Canal) at the end of 2012 I see this idea as significant.
In Christian mythology, Venus or the Morning Star is associated with the Devil or Lucifer. Could potentially be tied into the return of Lucifer. Meanwhile, many Christian groups are claiming that these are the end times and that the second coming of Christ is near - this would presumably be preceded by the return of Lucifer according to Biblical prophecies.
There are theories going around at the moment about mass rituals being run by Elite Satanist groups involving Venus/Lucifer and basically trying to resurrect Lucifer. According to those theories this also ties in with a lot of what NASA is doing recently, the Chille mining accidents and possibly even 9/11 to name a few. From what I understand the timing of these events is linked to the passage of Venus. These ideas are obviously heavily rooted in Christianity as well.
As for Timewave Zero - the last Venus transit was around 1980 which is roughly the time period we have been resonating with for the last year or so. Obviously there's not a solid correlation because the transit always takes 8 years and happens every 110-130 years from the dates as posted. I still found it interesting that the last transit also happened during a time in which great changes were taking place and that we have been resonating with this time recently.
I think that just about covers it - or at least my very limited understanding of it. I don't agree with all of these ideas but I think its interesting that Venus and its transit are significant to many different religions and theories. All roads lead away from Rome and IMO all signs point to something significant going on around here.
